Switch on your phone without a sim card. You should be prompted to "Start Phone Without SIM Card" or similar. Click "Accept" or "OK". Your phone is now in offline mode.

Connect your Nokia phone to the PC using the USB Cable. Your phone will display several options, "PC Suite Mode", mass storage mode etc... stay in this screen, do not select any of the options.

Start the "SendCodeUsb" application you downloaded earlier and click on the "Read Phone Info" button. The application should display several lines of information. If it says "not found" replug your phone into the usb, and then click read phone info.

If the application still displays "Not Found", your "USB Cable Drivers" are not correctly installed. In this case you will need to uninstall, then re-install the USB Cable Drivers. This procedure will not work unless the drivers are correctly installed. Trying an alternative USB Port may also help. DO NOT move on to the next step until you have successfully installed the USB Cable Drivers and the software can read the information from the phone.

Now make sure you check the "Check For Fbus" checkbox. Also make sure the "Level(1-7)" selection is set to the appropriate carrier
